在多款车型实践基础上,总结了一种提升汽车覆盖件材料利用率的方法,给出了工作流程图,即在同步设计开发或油泥车阶段,应用板料成形CAE模拟手段,通过优化零件边界、工艺补充面、坯料形状的交互试错,获得了优化的零件状态和合理的工艺方案,实现了材料利用率的最优化;以B车型的轮罩外板零件为实例,采用上述方法可将该零件的材料利用率从38.04%提升到56.67%,每台节省材料3.61 kg、实现效益22.96元,证实了该方法有效可行。 Based on the practice of many vehicle models, a method to improve the material utilization rate of automobile panel is summarized. The working flow chart is given, that is to apply the CAE simulation method of sheet metal forming in the stage of synchronous design and development or sludge car, Boundary, process replenishment surface and blank shape interactive trial and error, and obtain optimized parts state and reasonable process plan to achieve the optimization of material utilization rate. Taking B wheel cover parts as examples, the above method can be used The material utilization rate of this part was raised from 38.04% to 56.67%, each material saved was 3.61 kg, and the benefit was realized was 22.96 yuan, which proves that the method is effective and feasible.
